Newly released video shows Mutassim Gaddafi, son of Muammar and former national security adviser in his father's regime, calmly smoking a cigarette shortly before his death.

The above video appears to show a bloodied Mutassim after being captured by Libyan rebels yesterday followed by gruesome footage of his dead body. According to ABC News, Mutassim's brother Saif Gaddafi is the only Gaddafi child unaccounted for: the other sons are dead and the daughters are exiled.
